  The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and elements.

  Referring generally to FIG. 1, a food waste disposer 10 of the present disclosure includes an upper food transport portion 12, a lower motor portion 14, and an intermediate grinding disposed between the food transport portion 12 and the motor portion 14. Part 16. The food transport 12 includes a housing 18 that forms an inlet 20 at its upper end for receiving food waste and water in direction “A”. The housing 18 also includes a second inlet 22 that receives water and food waste discharged from the dishwasher 124 (FIG. 10) in the direction “B”. The food transport unit 12 transports food waste and water to the central ground portion 16.

  The motor unit 14 includes a motor 24 that provides rotational movement to the motor shaft 26, and the motor 24 may be an induction motor as an example. The motor 24 is surrounded by a motor housing 28 having an upper frame 30 and a lower frame 32, and either or both are made of a metal such as aluminum, a polymer material, or a composite material. According to some embodiments, a fluid seal 34 is provided that generally conforms to the upper surface shape of the upper frame 30 and acts to prevent fluid or food waste from entering the motor section 14. The fluid seal 34 may be formed by a molding process from a polymeric material such as, but not limited to, polypropylene or polyamide.

  The ground portion 16 can include a support plate 36 connected to rotate relative to the motor shaft 26. The support plate 36 can be connected to a ground or rotating plate 38. The water and ground food waste mixed in the slurry are collected below the support plate 36 and the rotating plate 38 in the waste receiving cavity 40 that discharges in the discharge direction “C” via the discharge port 42. In some embodiments, the rotating plate 38 is circular and is fixedly attached to the motor shaft 26. The rotating plate 38 can also be secured to the motor shaft 26 by swaging, welding, an interference fit, or using other known securing techniques.

  The motor unit 14 may further include a winding 44 that forms an induction electromagnetic field for the motor 24. An electronic control 46 may be provided that controls the operation of the motor 24 such as operating speed, stalled or overheat shut-off. A conditioning shell or outer housing 48 may also be provided to enclose one or more layers of the sound insulation 50. According to some embodiments, the outer housing 48 and the soundproofing part 50 are provided around both the motor part 14 and the food conveying part 12 for maximum acoustic attenuation.

  The ground portion 16 has a ground cavity 52 disposed above the rotating plate 38 to receive food waste and a large amount of water. Food waste and a large amount of water may be received through the inlet 20, through the second inlet 22, or both. At least one and in some embodiments, a plurality of fixed projections or blades 54 extend upward from the rotating plate 38 and rotate at the same speed as the rotating plate 38. The food waste is pushed outward by centrifugal force toward the blade 54 or the blade 54 forcing the food waste into contact with the cutting edge or teeth defined by the plurality of openings 56 in the fixed shredder ring 57. The fixed shredder ring 57 is fixed in contact with the inner surface of the support wall 58 so as to be fixed to the rotating plate 38. Food waste is ground between the outer edge of the blade 54 and the cutting edge of the opening 56, and ground food waste particles having water in the form of a slurry are passed through the opening 56 in the waste receiving cavity 40. Move downward as seen in FIG.

  At least one and, in some embodiments, a plurality of rotatable projections 59 are provided (first projection 59 and second projection 59) to assist in transferring food waste toward the blade 54. Each of which is connected to the rotating plate 38 and / or the support plate 36 using fasteners such as a rotating rivet 60. A rotating rivet 60 (or similar rotatable connector) allows the protrusion 59 to rotate freely with respect to the rotating plate 38. The protrusion 59 functions to keep the food waste moving outward, thus preventing food waste accumulation in a fixed position relative to the rotating plate 38 outside of the blade 54.

  According to some embodiments, at least one fluid recovery member or tube 61 is disposed on the rotating plate 38 to fluidly connect to the waste receiving cavity 40 and the ground cavity 52. The rotational movement of the rotating plate 38 and the shape and direction of the tube 61 create a difference in fluid pressure between the waste receiving cavity 40 and the ground cavity 52. Due to this pressure difference, a portion of the slurry in the waste receiving cavity 40 is pulled back into the ground cavity 52. A portion of the recovered slurry can vary depending on the size of the tube 61, and in some embodiments is about 20% to 25% of the volume of the waste receiving cavity 40. Thus, the water portion of the returned slurry is “recovered” and is available to help crush further food waste within the crush cavity 52. The food scrap particles ground prior to the returned slurry do not significantly reduce the disintegrating ability of the disposer 10.

  Referring now to FIG. 2, an exemplary configuration of rotatable protrusion 59 and fluid recovery tube 61 is shown. In the exemplary embodiment of FIG. 2, two fluid collection tubes 61 are shown. It should be understood that there can be any number of fluid collection tubes 61 including one. In the example shown here, the rotatable protrusions 59, 59 'are arranged at an interval of about 180 ° from each other and at an interval of about 90 ° from each of the collection tubes 61 arranged in an opposing relationship. Each of the rotatable protrusions 59 includes first and second wings 62, 64 that assist in advancing food waste outward by the rotational movement of the rotating plate 38. At least one, and in some embodiments, the plurality of drain holes 66 are formed in the waste receiving cavity 40 by gravity after the remaining amount of water or slurry in the ground cavity 52 has stopped rotating the rotating plate 38. Extends through a rotating plate 38 and a support plate 36 (if used).

  As best seen with respect to both FIGS. 2 and 3, fluid recovery tubes 61, 61 'define fluid recovery passages 68, 68', respectively. The fluid recovery passages 68, 68 ′ open continuously between the waste receiving cavity 40 and the ground cavity 52. A motor shaft that receives the opening 69 is also provided on the rotating plate 38. In the illustrated embodiment, the fluid collection tubes 61, 61 ′ are fixedly attached to the upper surface 72 of the rotating plate 38 using a weld joint 70 and define an angle α with respect to the upper surface 72. The angle α can be any angular range from about 5 ° to about 85 °, and according to some embodiments, selected from angles within a range of about 30 ° to 50 °. The rotating plate 38 rotates in a predetermined direction, and in the embodiment of FIG. 2, the rotation is counterclockwise, which defines the direction of rotation “D”. The first portion of each fluid collection tube 61 may terminate coextensive with the upper surface 72 of the plate so as to define the discharge end 76 or extend above the upper surface 72. Can exist. The second portion of each fluid collection tube 61 extends below the lower surface 74 of the plate and includes an inlet end 78. Based on the direction of rotation “D”, the fluid recovery tube 61 in the upper part of FIG. 3 moves in the direction of movement “E”, and due to the angle α, the inlet end 78 is substantially perpendicular to the lower surface 74. Define a leading edge that can be directed. Accordingly, the inlet end 78 acts to draw water and slurry from the waste receiving cavity 40. The water / slurry mixed stream is also caused to some extent due to the higher fluid pressure at the inlet end 78 compared to the discharge end 76, the fluid pressure as the angle α increases and the rotating plate As the rotational speed of 38 increases, it can increase.

  To maximize fluid flow through the fluid collection tube 61 and minimize the possibility for cavitation noise, in some embodiments, the discharge end 76 of each fluid collection tube 61 is on the upper surface 72. An exit surface is defined that is generally parallel to the surface. The upper portion of the tube 61 at the discharge end 76 can be flush with the upper surface 72 or can extend above the upper surface 72 by a dimension “F” and the tube at the inlet end 78. The lower portion of 61 extends below the lower surface 74 by a dimension “G”. The dimensions “F” and “G” can vary, particularly with respect to the dimensions of the inlet end 78 and the fluid recovery passage 68, and are generally limited by the depth of the ground cavity 52 and the debris receiving cavity 40. The flow emerging from the discharge end 76 is initially moving in a direction “H” that varies directly with an angle α. The discharged fluid is then dispersed outward due to centrifugal acceleration. The dimension “F” can vary from zero to the maximum height available in the ground cavity 52 when the discharge end 76 is substantially flush with the upper surface 72. However, tests have shown that a reduction or zero value for dimension “F” further prevents food waste from adhering to the fluid collection tube 61 or being advanced further away from the blade 54. Yes. If the distance “F” is zero or nearly zero, the weld joint 70 may be positioned below the rotating plate 38.

  4 and 5, in other embodiments of the present disclosure, separately connected collection tubes 61 are similarly formed by stamping, drawing or molding processes from the material of the rotating plate 80. The functional member can be replaced. A rotating plate 80, similar to the rotating plate 38, has one or more rotatable protrusions 59 connected thereto by fasteners, such as a rotating rivet 60, and one or more discharge holes 84, similar to the discharge holes 66. An upper surface 82 can be included. The rotating plate 80 includes at least one similarly formed and, in some embodiments, a plurality of fluid recovery members 86 (two fluid recovery members 86, 86 'are shown). Similar to the rotating plate 38, the rotating plate 80 is adapted to rotate in a predetermined direction, such as the rotational direction “D”, and causes the fluid recovery member 86 to move in the moving direction “E”.

  As best seen with respect to FIG. 5, each fluid recovery member 86 is formed by moving a portion of the rotating plate 80 away from the lower surface 88 or relative to the lower surface 88. They are arranged at intervals. In some embodiments, each fluid recovery member 86 may also be formed by moving a portion of the rotating plate 80 away from the upper surface 82 or spaced from the upper surface 82. Can be placed. The fluid recovery inlet 90 is formed below the lower surface 88 at the end of the extending wall portion 92. A generally smooth fluid transfer surface 94 is formed from the fluid recovery inlet and extends to a wall extension 96 formed above the upper surface 82. Similar to the fluid recovery tube 61, water and slurry from the waste receiving cavity 40 flows into the fluid recovery inlet 90 in the inlet flow direction “K” and is directed and discharged along a path defined by the fluid transfer surface 94. In the direction “L”, it is discharged into the crushing cavity 52 above the upper surface 82. Wall extension 96 and fluid transfer surface 94 define an angle β with respect to upper surface 82. The angle β can be any angle within the range specified above for the angle α in FIG. The fluid recovery member 86 can be similarly disposed around the rotating plate 80 when the fluid recovery tube 61 is disposed. The fluid recovery member 86 may be formed from the material of the rotating plate 80 using any one or more of drawing, stamping, stamping, casting, molding, or similar processes. The distance of the extending wall 92 extending below the lower surface 88 and the distance of the wall extension 96 above the upper surface 82 when the drawing process is used were initially selected for the rotating plate 80. It is substantially controlled by the thickness.

  Referring now to FIGS. 6 and 7, the fluid collection tube 61 can be rectangular in cross section, as shown, but is not limited to square, circular, elliptical, and others. Other shapes such as a polygon can be used. The tube wall thickness “J” of the tube wall 98 meets the desired cross-section of the fluid recovery passage 68 and / or the requirements for welding or fixedly connecting the fluid recovery tube 61 to the rotating plate 38. Can change. The food waste disposer 10 of the present disclosure is not limited by the shape of the fluid recovery tube 61. The tube 61 in the illustrated rectangular example includes first and second sidewalls 100, 102 and a tube front wall 104 that acts as the front surface of the tube 61 in the direction of travel “E”. The fluid flowing into the inlet end 78 is redirected by the tube rear wall 106 in the fluid discharge direction “H”.

  With reference now to FIG. 8, an exemplary shape of the recovery member 86 includes a generally U-shaped fluid recovery passageway 108 defined by a fluid transfer surface 94. The fluid flows into the fluid recovery passageway 108 at the inlet surface 110 that defines the curved passage wall 112 of the extending wall 92 formed below the lower surface 88. The shape of the fluid recovery passage 108 is not limited to the U-shape shown, but may be rectangular, elliptical, circular, V-shaped, etc. at the discretion of the designer.

  As best seen in FIG. 9, the location of the front or inlet end 78 of the fluid recovery passage 68 is such that a portion of the water / slurry arranged for discharge from the disposer 10 can be recovered. Can be directed against outlet 42. The position of the inlet end 78 can also be raised or lowered from what is shown within the constraints of the waste receiving cavity 40. The inlet end 78 can also be cleaned as needed by removing any drain fitting from the outlet 42. A further advantage of the orientation and design of the inlet end 78 is a passage through the waste receiving cavity 40 proximate the outlet 42. The inlet end 78 can remove or clean food debris such as a food bunch that bypasses the interface of the blade 54 and the cutting edge or teeth formed by the opening 56. This food waste may otherwise accumulate in the area of the outlet 42. Accordingly, the inlet end 78 of the fluid recovery tube 61 can provide the disposer 10 with a “self-cleaning” function.

  Still referring to FIG. 1, during operation of the food waste disposer 10, the food waste sent to the ground portion 16 by the food transporter 12 is the teeth formed by the rotatable protrusion 59 and the opening 56 of the shredder ring 57. Is pushed out by the blade 54 in contact with the blade. The teeth crush (as shown in FIG. 1) or grind food waste into sufficiently small particulate material to pass from above the rotating plate 38 to below the rotating plate 38. Due to gravity, the particulate matter passing through the opening 56 falls onto the polymerization fluid seal 34 above the upper frame 30 and together with the amount of water injected into the disposer 10 to form a water / debris slurry, Through the discharge pipe 114. A fluid tight seal is formed where the support wall 58 and the fluid seal 34 meet. The discharge pipe 114 can be connected to the discharge port 42 by a pipe nut 116. Other exemplary methods of connecting the food waste disposer to the drain tube 114 are listed in US Pat. No. 6,007,006 (Engel et al.), Shared by the assignee of the present disclosure, the subject matter of which Are incorporated herein by reference.

  A shredder ring 57 including a plurality of spaced openings 56 may also be fixedly attached to the inner surface of the support wall 58 by an interference fit, from other metal materials such as galvanized steel or stainless steel. Can be configured. The shredder ring 57 can also be formed from a non-metallic material such as a polymer or composite material. The shredder ring 57 can also be formed in the support wall 58 by molding or machining techniques. The support wall 58 can also be injection molded plastic, or can be formed from a metal such as powdered metal or steel, or can be formed by a casting process such as die casting or investment casting. The use of injection molded plastic allows the support wall 58 to be resistant to corrosion from contacting the shredder ring 57. However, the present disclosure is not limited to housings formed from injection molded plastic.

  With continued reference to FIG. 1, the rotating plate 38 and support plate 36 can also be replaced with a single-piece assembly to reduce the complexity of the manufacturing process and increase the integrity of the grinding mechanism. Alternatively, the rotating plate 38 and the support plate 36 can be attached by mechanical connectors (such as welding or rivets) or adhesive. Installing the parts reduces the relative movement between the two parts and minimizes the number of parts that will be handled during final assembly.

The rotating plate 38 (and the rotating plate 80) may be formed from a flat sheet of stamped or shaped metal. Alternatively, the rotating plates 38 and 80 can be formed by a powdered metal method, by an injection molding method such as insert plastic injection molding or metal injection molding, or by a casting method such as die casting or investment casting. The rotating plate 38 in some embodiments has a thickness range from about 0.040 inches to about 0.100 inches (about 0.102 cm to about 0.254 cm) . In some embodiments, the rotating plates 38 and 80 are comprised of cold-rolled steel sheets that are galvanized on both sides and have a thickness of about 0.071 inches (about 0.180 cm) . The rotating plates 38 and 80 can also be composed of stainless steel, powdered metal, or other metallic materials such as casting materials, or non-metallic materials such as plastics.

The fixed shredder ring 57 may be formed from a stamping method, a powder metal method, an injection molding method such as insert plastic injection molding or metal injection molding, or a casting method such as die casting or investment casting. When constructed from stamped metal, the fixed shredder ring 57 in some embodiments has a thickness range from about 0.030 inches to about 0.090 inches (about 0.076 cm to about 0.229 cm). Have According to some embodiments, the fixed shredder ring 57 is constructed from a cold rolled steel sheet that is galvanized on both sides and has a thickness of about 0.055 inch (about 0.140 cm) . The fixed shredder ring 57 may also be formed from other metallic materials such as stainless steel or non-metallic materials such as plastic. The openings 56 may be provided with different shapes so as to grind differently sized or density food particles as required. The exposed height of the opening 56 above the upper surface 72 of the rotating plate 38 in some embodiments ranges from about 0.180 inches to about 0.350 inches (about 0.457 cm to about 0.889 cm) .

  Referring now to FIG. 10, in an exemplary implementation, the food waste disposer 10 is attached to a sink 118. A large amount of water is used to form a waste / water slurry that enhances the discharge of ground waste particles to the drain 120 or other discharge location. The water source can be a faucet assembly 122 whose volume flow is manually controlled, or the dishwasher discharge pipe 126 connected to the second inlet 22 for subsequent grinding by the disposer 10. Through the dishwasher 124 together with food waste. Power for the motor 24 is provided via a power cord 128.

  Referring now to FIG. 11, in an additional embodiment of the present disclosure, water recovery for food waste disposer 10 is also located in drainpipe 114 or drainpipe 120 (such as a flow controller or pressure switch). It can be controlled by the use of one or more control devices including a discharge flow control device 129 or a discharge flow control device 130 in the dishwasher discharge pipe 126 (such as a flow control device or a pressure switch). Devices 129 and 130 can operate in several ways: 1) A method of reducing the total amount of water used in operation by reducing fluid / slurry discharge 2) Operation of food waste disposer 10 when flow rate or fluid pressure is detected in, for example, dishwasher discharge pipe 126 Or 3) when a diverter that diverts a portion of the fluid / slurry drains through the drain tube 114 and is diverted to the waste receiving cavity 40 of the food transport 12 via the separation channel How to be returned.

  A control device operable as a discharge flow control device 130 may be placed in contact with the tube surface or in fluid communication with the water / slurry mixture and the presence of the water / slurry mixture in the dishwasher discharge pipe 126 from the dishwasher 124. The food waste disposer 10 is operable to be activated by receiving a signal indicating. For example, the controller 129 operable as a discharge flow control switch is in contact with or within a tube defining a waste disposer discharge tube operable to receive a water / slurry mixture discharged from the food waste disposer 10. It can be placed in fluid communication with the fluid. The controller 129 controls operations such as shutting off food waste disposers by receiving signals indicating a lack of water / slurry mixture flow, or reuses a portion of the water / slurry mixture that returns to the disposer 10. Operable to open the distribution device.

In some embodiments, a separate pump 131 (not shown) is also used with one or more controllers 129, 130 to direct a partial return flow of the water / slurry mixture to the food waste disposer 10. Can be done. The discharge from the pump 131 (not shown) can be connected directly to the second inlet 22 if the dishwasher 124 is not connected, or a check valve to prevent backflow towards the dishwasher 124, etc. The backflow prevention device 133 (not shown) can be fed through a tube 132 (not shown) that can be connected in place into the dishwasher discharge pipe 126. The discharge of the water / slurry mixture from the disposer 10 can also be returned directly to the ground 16 via a tube 132 (not shown) without using a pump 131 (not shown) . Either the controller 129 or 130 or the pump 131 (not shown) can also be electrically connected to an electronic controller 46 that turns the disposer 10 and / or the pump 131 (not shown) on or off.

  An example of a device that can be used for the flow control switch 129 is the FX series electronic flow control switch available from Instruments and Controls of Ameritol, Vista, California. Examples of devices that can be used for the flow control device 130 are ultrasonic flow sensors such as the flow sensor ABB U2500 available from the ABB Group of Asa Brown Boverri, Zurich, Switzerland, and in-line flow meters from Omega Engineering. In-line flow meter such as model FV100.

  Referring now to FIG. 12, according to other embodiments of the present disclosure, the fluid collection tube 134 ends substantially at the upper surface 72 of the rotating plate 38, or is flush with the upper surface 72. The fluid recovery tube 61 is changed. An alternative weld joint 136 may be provided to join the fluid recovery tube 134 to the lower surface 74 of the plate. The tube inlet end 138 acts as the front surface of the tube 134 in the direction of travel “E”. Fluid flowing into the inlet end 138 is redirected by the tube rear wall 140 into the fluid recovery passage 142 that directs flow in the fluid discharge direction “H”. Similar to the fluid collection tube 61, one or more fluid collection tubes 134 may be used, each oriented at an angle α relative to the upper and lower surfaces 72,74.

  Additional elements can also be provided to assist in the transfer and efficient handling of food waste. These elements can include rotating spikes, shunts, and breakers disclosed in Anderson et al., US Pat. No. 6,439,487, shared by the assignee of the present application, whose subject matter is , Incorporated herein by reference.

  The water reuse food waste disposer system of the present disclosure provides several advantages. By directing a portion of the water / slurry that would otherwise be discharged directly back to the disposer mash, the water in the recycled portion can be further used for further food waste treatment. By directing the fluid collection tube or flow member at a predetermined angle through the grinding plate's rotating plate, the rotating plate's rotational speed is required to return a portion of the water / slurry without the need for additional pumps or equipment. Generate a differential pressure. The amount of fluid / slurry recycled can be predetermined by the size, depth, and amount of the fluid collection tube or flow member. Some consumers use warm water or hot water, and some consumers also use soap or other chemicals to clean the disposer during and after grinding. Having a food waste disposer allows the dishwasher to be used while draining heated reclaimed soapy water to better clean and clean the disposer both during and after crushing Only controlled. Reclaimed water can be used for grinding without increasing costs. A further advantage of recycling a portion of the water / slurry mixture is that additional grinding can occur that can further reduce the size of the particles that assist in the discharge of the slurry.
